APPARATUS FOR CARBONATING AND DISPENSING BEVERAGES.

Specification of Letters Patent.

Patented Oct. 5, 1999.

Application filed May 25, 1907. Serial No. 375,610.

To all whom it may concern:

Be it known that we, Lnon C. PARIS and Tnonas MiLLWARD, both citizens ofthe United States, and residents of the city and county of SanFrancisco, State of California, have invented certain new and usefulImprovements in Apparatus for Carbonating and Dispensing Beverages, ofwhich the following is a specification in such full and clear terms aswill enable those skilled in the art to construct and use the same.

The principal object of this invention is to produce a carbonatedbeverage from a non-carbonated water in a single operation, and withoutthe use of power in excess of that stored in the water mains and theusual tank of liquid CO Another object of the invention is to produce acarbonated beverage in such a machine as to enable the small dealers tohave one for each fountain, as is not the case where large and heavypumps are used.

A further object of the invention is to produce a machine that will havea large capacity even though it is a small machine and cheaply made.

A further object of the invention is to produce a machine that will havemeans to take the pressure off the carbonated water prior to its escapetherefrom, since when the water runs violently out of a bottle orcontainer under a heavy pressure the agitation causes the CO to leavethe water quickly, while if the water is allowed to run 01f easily andunder a pressure no greater than that of the atmosphere and its ownweight the gas will not leave it for a considerable time.

Another object of the invention is to provide means to allow a smallstream of the carbonated water to flow under a high pressure into theglass of syrup in order that the syrup may be completely stirred upprior to the time the main body of the water is allowed to run into theglass under practically no more pressure than that of its own column.

A further object of the invention is to carbonate the water in anapparatus that is associated with the fountain, and which takes up nomore space than the common fountains now in use, said action takingplace at the time the glass of water is to be drawn from the machine.

In the drawings in which like numerals of 1 not allow them reference areapplied to like parts throughout, Figure 1 is a side elevation of themachine, Fig. 2 is a plan of the machine, with the container shown indotted lines only, and with one of the mixing chambers broken away toshow the bafiie plates, Fig. 3 is a front elevation of the machine, Fig.4: is a vertical section of the fountain faucet, Fig. 5 is a detailshowing the spring in the handle knob to keep the high pressure valverod off the valve stem, Fig. 6 is a view showing one of the perforatedbaflle plates. Fig. 7 is a diagram showing the inlet end of the mixingchamber in side elevation as in Fig. 1, and illustrating the connectionof the'gas nozzle and water pipe, and Fig. 8 is a view of the wedgesfrom the opposite side of Fig. 1.

The machine rests on the bars 1 and 2 which have vertical extensions tothe container 3 to the bottom of which they are secured at l, theuprights being bent over for that purpose as shown at 5. Carried by theuprights is a square rod 7 which passes through the straps 6, 6 on thevertical parts of the bars 1 and 2. This rod is square in order thatwhen the wedges carried by it are pushed against the valve stems it willto be displaced. Around the rod 7 is coiled the spring l0, which is Iquite heavy and is for the purpose of keeping the rod in the positionshown in Fig. 1, which it accomplishes by acting on the lug 41 which issecured to the rod 7. The front end of this rod 7 is bent at rightangles with the body of the rod and takes in a slot in the handle 8,said slot being necessary in order that the handle may be moved in anarc while the rod moves straight forward, or back as the case may be.The other end of the rod 7 has secured to it the wedge bar 9 and towhich are secured the wedges 10, 10, 10 and the wedge 11 for releasingthe pressure on the container when the desired amount of water has beenallowed to collect therein.

The wedges 10 and 11 are for the purpose of opening the valves 13 ofwhich there are four, said wedges bearing on the tops of the valve stems12. Into the outer valve 13 is screwed the water supply pipe 14L, whichis connected with any water main which may be under a good pressure. Thenext valve 13 has screwed into it the pipe 15, which leads to the tankof CO (not shown) which I t th thi d l side of the fourth valve 13, saidvalve opening into the air.

The gas and water supply pipes being connected with a full gas tank andthe water main respectively the machine operates as follows: In thenormal position all the valves are closed, but the operator desiring todraw a charge of water from the machine he first pushes the handletoward the container 3. This operation opens the valves operated on bythe wedges .10, with the re sultthat the gas and water rush through themixer and up into the container, continuing so to do till the pressureof the air in the container is the same as the pressure of gas and waterin the mixer, the container being of such a size as will allow thecollection of about a pint of water at one time. It takes but a veryshort t me for the water to collect in the container and as soon as theoperator thinks the container has a charge he draws the handle towardhim. This act closes the valves under the wedges 10, and as soon as hedraws the handle a short distance farther toward him the wedge 11 opensthe valve 13 on the stem of which it operates. This valve is openedbefore the cut 30 reaches the point at which it will allow the water topass out of the container, and in this way the compressed air is allowedto escape from the container, and a further motion of the handle opensthe valve 29 and allows the water to run quietly out of the machine tothe glass. The reason the pressure is taken off the container is toallow the water to run out quietly in order that the gas may not bedisturbed, since when it is violently agitated it loses much of its gasand becomes flat. If the water is all allowed to run quietly into theglass it would not mix the syrup up with the same, so to mix the syrupwith the glass of water the valve 31 is provided.

Before the attendant runs the water from the container into the glass heholds the glass under the faucet 26 and presses on the rod 36, whichextends through the knob 37, and when the handle is in the normalposition the rod can reach the top of the stem of the valve 31 and openit. This allows a stream of water under a considerable pressure to flowinto the glass and since it is a small swift stream the syrup iscompletely stirred up, and made ready for the larger amount of water tobe run from the container.

It will be observed that the water may escape from the mixer through thepipe 33 even though there is no inlet valve open for the reason that themixer is under the pressure of the gas and water and the gas wouldalways collect to such an extent as to allow the required amount ofwater to pass through the valve 31.

h Iodifications of the invention is under a high pressure. valve 13 isconnected the pipe 16 having the vertical extension 17 connected withthe bottom of the container 3.

On the outlet side of the outer valve 13 is placed the pipe 18 whichleads to the end of the mixer 21, while from the outlet end of thesecond valve the pipe 19 extends, said pipe being connected with thepipe 18 as shown in Fig. 7, a nozzle 25 having a ver small opening beingplaced at the end of the mixer to direct the gas in the direction offlow of the water, and on the inlet side of the third valve 13 is placedthe pipe 20. This pipe 20 connects with the discharge end of the mixer23, both sections of the mixer being connected by means of the pipe 22.I t will be understood that the mixers may be of any desired length, orthat more than two might be used.

The mixers are square tubes having a se ries of perforated baflie platessecured there in, said plates being set as shown in Fig. 2, for thepurpose of causing the water and gas to be intimately mixed passagethrough the mixer. The holes in the battle plates 24- are for thepurpose of further mixing the water and gas, but in practice they wouldbe very much greater in number than is shown in the illustration.

The fountain faucet 26 is carried by the pipe 32, which in turn isconnected with the bottom of the container 3 at its lowest point. Thisfountain faucet 26 has a large passage 27 to the nose 34 cut off bymeans of the valve stem 29, said stem having a portion 30 cut away toallow the water to run out of the container when the valve is turned tothe proper position. The illustration in Fig. 4 is of the valve in thenormal position as determined by the spring 4-0, and said illustrationis the same as the position of Fig. 1.

In the upper part of the fountain faucet 26 there is a second valve 31,which is of the same general type as the valves 13, in a passage 28which leads to the nose of the valve. This small passage is for thepurpose of providing means to supply a small fine stream of the waterunder a high pressure to stir the 'yrup in the glass. Connected withthis small passage is the pipe 33 which leads to the bottom of the mixer23, said pipe being connected with the bottom of the mixer in order toinsure the water reaching the valve.

It will be observed that the handle 8 is pivoted by means of the valvestem 29, one arm of the handle passing on each side of the valve body.This handle has a knob 37 through which passes the rod 36, said rodbeing held in the position shown by means of the spring 39, the knob tohold Leading out of the top of the container 3 is the pipe 35 whichconnects with the inlet within the scope of the appended claims arereserved.
